``CROSS_COMPILE`` is used to set a command line flag: ``--target=<triple>``. For

LLVM Utilities
--------------
LLVM has substitutes for GNU binutils utilities. They can be enabled individually.
The full list of supported make variables::
make CC=clang LD=ld.lld AR=llvm-ar NM=llvm-nm STRIP=llvm-strip \ make CC=clang LD=ld.lld AR=llvm-ar NM=llvm-nm STRIP=llvm-strip \
OBJCOPY=llvm-objcopy OBJDUMP=llvm-objdump READELF=llvm-readelf \ OBJCOPY=llvm-objcopy OBJDUMP=llvm-objdump READELF=llvm-readelf \
HOSTCC=clang HOSTCXX=clang++ HOSTAR=llvm-ar HOSTLD=ld.lld HOSTCC=clang HOSTCXX=clang++ HOSTAR=llvm-ar HOSTLD=ld.lld
To simplify the above command, Kbuild supports the ``LLVM`` variable:: ``LLVM=1`` expands to the above.
make LLVM=1
If your LLVM tools are not available in your PATH, you can supply their If your LLVM tools are not available in your PATH, you can supply their

as an environment variable when running scripts that will eventually run
``make``.
Omitting CROSS_COMPILE Cross Compiling
---------------
A single Clang compiler binary (and corresponding LLVM utilities) will
typically contain all supported back ends, which can help simplify cross
compiling especially when ``LLVM=1`` is used. If you use only LLVM tools,
``CROSS_COMPILE`` or target-triple-prefixes become unnecessary. Example::
make LLVM=1 ARCH=arm64
As an example of mixing LLVM and GNU utilities, for a target like ``ARCH=s390``
which does not yet have ``ld.lld`` or ``llvm-objcopy`` support, you could
invoke ``make`` via::
make LLVM=1 ARCH=s390 LD=s390x-linux-gnu-ld.bfd \
OBJCOPY=s390x-linux-gnu-objcopy
This example will invoke ``s390x-linux-gnu-ld.bfd`` as the linker and
``s390x-linux-gnu-objcopy``, so ensure those are reachable in your ``$PATH``.
``CROSS_COMPILE`` is not used to prefix the Clang compiler binary (or
corresponding LLVM utilities) as is the case for GNU utilities when ``LLVM=1``
is not set.
The LLVM_IAS= argument
---------------------- ----------------------
As explained above, ``CROSS_COMPILE`` is used to set ``--target=<triple>``. Clang can assemble assembler code. You can pass ``LLVM_IAS=0`` to disable this
behavior and have Clang invoke the corresponding non-integrated assembler
instead. Example::
If ``CROSS_COMPILE`` is not specified, the ``--target=<triple>`` is inferred make LLVM=1 LLVM_IAS=0
from ``ARCH``.
That means if you use only LLVM tools, ``CROSS_COMPILE`` becomes unnecessary. ``CROSS_COMPILE`` is necessary when cross compiling and ``LLVM_IAS=0``
is used in order to set ``--prefix=`` for the compiler to find the
corresponding non-integrated assembler (typically, you don't want to use the
system assembler when targeting another architecture). Example::
For example, to cross-compile the arm64 kernel:: make LLVM=1 ARCH=arm LLVM_IAS=0 CROSS_COMPILE=arm-linux-gnueabi-
make ARCH=arm64 LLVM=1
If ``LLVM_IAS=0`` is specified, ``CROSS_COMPILE`` is also used to derive Ccache
``--prefix=<path>`` to search for the GNU assembler and linker. :: ------
make ARCH=arm64 LLVM=1 LLVM_IAS=0 CROSS_COMPILE=aarch64-linux-gnu- ``ccache`` can be used with ``clang`` to improve subsequent builds, (though
KBUILD_BUILD_TIMESTAMP_ should be set to a deterministic value between builds
in order to avoid 100% cache misses, see Reproducible_builds_ for more info):
KBUILD_BUILD_TIMESTAMP='' make LLVM=1 CC="ccache clang"
